WASHING MACHINE.

Application filed April`30, 1920. Serial No. 377,945.

To all whom 'it may concern Be it known that I, Ronnn'r LnLAND KIN- CAID, a citizen of the United States, vand a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful l/Vashing Machine, of which the following is a specification.

This invention relates to washing machines and has for its object a machine which is particularly simple in construction, eco- "nomic'al in manufacture, and highly eiicient,

rapid yand durablein` use, and also which embodies in one structure without complex parts, the vacuum principle of some washing machines, and the sloshingor waterfall principle of other machines.l The invention con- A suitableform,

ing hercshown as rectangularin plan and' sists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. 4

'Figure 1 is a plan view, partly broken away, of a washing machine embodying my invention.

yFigure 2 is a vertical sectional vielw. Figure 3 isa detail view of the means for holding the clothes receptacle elevated.

Figure 4 is an enlarged fragmentary viewl of the connection between the actuating mechanism and the rocking receptacle. y

Figure 5 is an enlargeddetail view `on line 5 5, Fig-4.

as having a cylindric concave bottom 2. The tub is supported on a suitable frame `3 is provided with a suitable cover 4., rThe means for supporting the clothes is here `shownfas a receptacle 5 supported in the tub to move or oscillate about an axis substantially coaxial with the cylindric bottom of the tub, the receptacle'having a cylindric tacle.

This washing machine comprises, gener` and bottom concentric with, and-spaced apart from, the bottom 2 of the tub, and having openings or passages for the fluidi These openings are perforatlons 7 in the `slats or" boards forming the bottom but may be provided by spacing said slats apart.

rThe receptacle 5 is provided with axles or `I studs 8 at its ends which bearings 9 normally resting in seats l10 provided inblocks 11 resting on angle irons `11a secured to the inner faces of the end walls of the tub. The bearings 9 'are provided at the lower ends of links 12 forming part of the mechanism to `be presently described,"for lifting the receptacle 5out of its normal position. The heads or end walls 13 ofthe receptacle 5 are higher than the top edges of are journaled inV the cylindric bottom 6, and the edges 14: y

thereof incline upwardly and inwardly from the edge of the cylindric bottom 6 to provide" clearance forrocking movement of the receptacle. rlfhe central part of the top edges of said headsincline downwardly at 15 toward the axis of the receptacle. Top pieces or boards '16 are secured to the heads 13 at the clothes from tumbling out during the oscillationof receptacle. Also braces as slats 17 connect the end Walls or heads of the recep-y The means for discharging or lifting'the iiuid or water from the bottom fof the `tub `and discharging it into the receptacle 5, as"

edges of the cylindric bottom 6 to hold the here illustrated, comprises blades or paddles 18 projectingfrom the receptacle 5 into the space between they receptacle and thebottom of the tub, these bladesbeing preferably rigidy with the receptacle and 'located on opposite sides of the axis of the receptacle and usually near the upper edges of the cylindric bottom 6 thereof, and running at their free edges close to the inner facey of the `cylindric bottom@ of the tub l; Dury ing `oscillationy of the receptacle the blade 18 moving upwardly lifts the fluid and dis` charges `it over the boards 16 and into the f receptacle or on the clothes therein. During this movement the other blade 18 ismoving downwardly under the iiuid into position" to liftthe fluid when the direction of movement of the receptacle is reversed. The Y blades cause a partial vacuum under the re` ceptacle, which draws the liu'id so discharged on the clothes,` through the clothes `back` into the bottom of the tub.` `For inl end anda creasing the downward suction through the receptacle a partition or bafleplate 19 may.Av be provided on the bottom of the tub be-l tween the paths swept by `the blades 18,

this baiie plate terminating nearthe bottom of the receptacle. The baiile plate 19 may however, be dispensed with.

Theblades 18 during their downward movement force the water beforev thein causingit to' surge through the perforations in the bottomof the receptacle be of any suit- The actuating means mayV i ableform, lsize and construction, and ashereI illustrated, consists of a rotating shaft 20 Journaled in bearings 21 in one end wall of thetub andhaving a crank 22 at its inner link 23 connecting thecrank and anupwardly extendingarm 24 fixed to a bracket 25 secured to the head ofthe re? ceptacle. Thev shaft-20 is connected to a vertically fextendingv shaft 26V yby inter-` ineshiiig `gears 27, 28, and the shaft 26,.

connected to a motor` not shown, mounted on theframe 3 beneath the tub. The vshaftsv and gearsare enclosed in acasing 29. The

link 2 3.isdetachablyconnected to one ofthe parts 22,.24fand as herevshowii, it is .de-

tachablymountedl on-the crank pin 30.0 As` Thehmeceptacle 5 is liftable out of its normal position from the f receptacle.

' which this-f result is obtainedV comprises a rock shaft 35 journaled in the opposite end walls of the tubV above and at vone side of the. receptacle, rock arms 36. mounted on the shaft neartthe end walls of the tub, the'1A arms-being connected to the upper" ends of the-links y1 2,a pedal 37V and connections'between the l,pedal and the shaft A36. The pedal 37 is pivoted to the frame'3 at 38 benea'th-the tub, and the connections comprise a rock arm 39 onv the outer endof the shaft 351" and a linkeOconnecting the pedal and,`

the-.arm L39'. Obviously, the receptacle can be raised4` after the cover of .theY tub is removed by merely steppiiigon the pedal 3 7; Preferably,.me ans is provided :for holding the receptacle elevated, this means being v here illustrated as ay detent or hook 41"'secured to the tub and coacting with the arm forV the purpose ofk elevating the same out ofthe water 'inthetub orfOran-ypther purpose as to more conven, ientlyplace` the clothes in` 0rv remove them.4 f The mechanism by `having a cylindrical bottom,y a .f ceptacle mounted in the tub Ato rock abouti@120 39 lwhen the arm is in itslowermost posi` y tion by reason ofthe pedal being depressed. The Itub isy provided with asuitable drain outlet 42.

As-the receptacle i isfv part cylindrical it may rock half way around 'either direction after disconnecting the link 23 from the crank 22 for the purpose of cleaning -the bottom of the tub' without removing the receptacle 5 therefrom. Also, the receptaclef- 5 can be completely inverted for thev purpose of cleaningfthe outer face of the-"bottom thereof. y Y

y ln operation,` the clothes are placed in the'` 1, receptacle and the cleansing fluid as hot 30 Vwater with a soapy substance therein filled inthe receptacle to the water line.` The jmotor is then started and'tlie'receptacleosfj` cillated causing the blades-.18 tol alternately.. discharge the water into thereceptacle,over` water through ythefclothes and the perforated bottom of the'tubl where it is againfll M lifted bythe blades 18. VVlien-this opera-gA tion is completed the fluid is drained off;4 rinsing water filled into thevtub and the op-"l eration repeated. The clothes rmay thenbeff removed and wrung. The usual'vwringer and attachments are not shown and are p rovided on the tuby 1 and theframe therefor. i

What I claim is: p 1. 'A washing machine comprising .a tub having a semi-cylindrical bottom, a lclothes f f receptacle mounted in the tub to rockabout a horizontal aXis concentric vwith the cylindrical bottomof the tub, the bottom ofthe receptacle having yopenings therein, blades? projecting` outwardly fromiiear 4the upper edgesof the bottoni of thereceptacle, blades runningclose, toytheebottom of they, tub and arrangedv to Vmove in 'i opposite Vhalves of the bottom of the tubfto liftfthe water alternatelyl over the upperqedgesof .the receptacle and onto thef'clothes thereinijllf when the blades approach'the limit-oftheirlthrow -in 4upward directions and-,to crea-te',t1 a partial vacuum behind "such blades,` for.y f

drawing the water downwardly through-thefy clothes and the perforated bottomof thereceptacle,"substantially as and for theYfpur-f. posedescribed.v I y 2. A washing machine comprisinga tub clothesfrehorizontal axis .concentric withjthe semig cylindricalxbottom of thereceptacle, there-j ceptacle having a substantially -openltop for..

.terminating'near the-inner faceof the .bot-w` tom .ofthe tub, and means for, rocking.,the

receptacle to cause thel blades to lift y'the 132 s55' A. opposite sidesy thereof and onto they clothes. 1\I The suction created lby `blades drawsythfe when the blades approach the limit of their throw upwardly, substantially as and for the purpose specied.

3. A washing machine comprising aftubV havin a cylindrical bottom, a clothes re-i ceptac e mounted in the tub to rock about a horizontal axis concentric with the semicylindrical bottom of the receptacle, the receptacle having a substantially open top for the inlet of water, the bottom of the receptacle having openings therethrough, blades projecting outwardly from near the upper edges of the bottom ofv the receptacle and terminating near the inner face of the bottom of the tub,V and means for rocking the receptacle to cause the blades to lift the water alternately over the upper edges of thereceptacle and onto the clothes therein when the blades approach the limit of their throw upwardly, the tub also having a blade arranged substantially centrally of its bot-` tom and projecting toward and terminating at its upper edge near the bottom `o the clothes receptacle7 substantially as and for the purpose set forth.` y

In testimony whereof I have hereunto signed my name, at Syracuse, in the county of Onondaga and State of N ewYork, this thdayz ofAril, 1920.
